Ordering number: EN742G Monolithic Linear IC LA4182 2.3 W 2-Channel AF Power Amplifier
Package Dimensions unit : mm . Built-in 2 channels enabling use in stereo and bridge applications. . amplifier High output: 2.3 W/channel, V = 9 V, R = 4 Ω, and W/bridge, R = 8 Ω. . 4.7 Minimum number of external parts required : 9 pcs. min. . (Stereo/bridge). Small pop noise at the time of power supply ON/OFF due to muting circuit. . built-in Good ripple rejection ratio due to built-in ripple filter. . Soft tone at the time of output saturation. . Good channel separation. . Voltage gain fixed at 45 dB (Bridge: 51 dB). Variable gain available with external resistor added. . voltage Easy to design radiator fin. CC L L 3022A-DIP12F [LA4182] SANYO : DIP12F Note) In general applications, heat generated in this package can be radiated through the Cu-foiled area of the printed circuit board, but since power dissipation Pd may be increased depending on the supply voltage and load conditions, it is recommended to use a fin additionally.
